How to Adjust

It’s important that the Levers feel stiff when they open and close—but not too stiff. The stiffness is about right if you can use just the pressure of your palm to close the Levers and only 2 or 3 fingers to open them. If your Folding Joints don’t feel quite right, don’t worry, you can adjust them. See video instructions below.

NOTE! An incorrectly adjusted Folding Joint may cause frame damage or result in rider injury. Please don’t adjust your Folding Joints without proper knowledge or tools.
